R&S FSV-K7/K7S
The temporary markers T1 and T2 are positioned n dB below the active reference
marker. The frequency and time position of these markers can be queried with
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:FREQuency?
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:TIME?. The bandwidth between
the markers can be queried with
RESult?.

Example:
Manual operation:
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:FREQuency?
This command queries the position of the n dB down markers on the x-axis when mea-
suring in the frequency domain.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweeps.
